For my Forever Tree NPC thread, I’m going to be statting up soon an Earth-L character who change his shape into essentially any living organism. The catch is—-it takes him weeks to effect small changes, with months for big changes and years for HUGE changes.

My question is: how do I best implement this? As a reminder, I’m asking how do you do this under M&M2e rules? Thanks!

An effect requiring longer than a full-round action to use is consid-
ered a drawback (see the Action flaw on page 102). Each step up
the Time Table is a 1 point drawback. The drawback cannot equal
or exceed the value of the associated power. So a power costing
10 points cannot have more than 9 points in this drawback (and
meaning the power takes three months to use!)
